To all whom it may' concern:

Be it known that I, Tmioooaa Barnum,

u citizen of the United States,-reaiding at,

irmfiioiu of which the following is a epecb v limit ion.

'lhe object of the present invention is to provide an' economical and practical plant for the instruction of cement buildings or structures, ond it is particularly adapted to the coimtruclion of large atnicttiree where iconomy in transportation and pouring of the cement is! an important factor in the l i 'lhe rpain object of the 'present invention is to provide 'u plant whereby the cement can be econoinii'iilly and rapidly delivered to any mrt of the werk or structure.

. Anot cr object of the invention is to provide-a complete apparatus for performingv the entire operation of preparing -and delivering thecement or concrete. ,4

Other objects of the invention ,will appear hereinafter.

The uccompnnying drawings illustrate my invention.

Figure 1 is a plan of the plant. Fig. 2 is n side elevation thereof. Fig. 3 is a section of the swivel for the delivery pipe.

and deliveri it by gravit to the int do-"l aired. A tolivger or frame whiclipiiiiiy' lio-I built in stages, as shown, so as to enable it" to be made of any required heighhsi'ippor ts} the elevator 9 which may consist of ancnd-j less cable or carrier inoiinted on Kiilleya 10 't carrying a bucket 11, which; in t vertical is adapted to pum" under theiiiouth of the delivery chute ti of the rotary'mixer 5, the bucket -11 being then in its lowest position. moana-'1 .is rovided for operating the elevator 9. A in or ho per 2 is provided at the top of the tower in 'tion to receive the contents of the bucket 11 when the latter is carried by the elevator carrier 9 to the top' 1 of the hop i 12 and dumped. Said hoppen" 12 has a elivery chute 18; extending' over' an open-top A hoist or other I cle or mouth i4 at the upper o! the eliyery chute 15. Said delivery chute ia mounted on a vertical mast 'l 16 to turn lioriaontally, said maat beingr sul ii cd if ported on the tower 8 and being neeeaaa ry .by lateral guy rgsea 8.
